Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a cam polishing machine. Background Art

[0002] Polishing technology is a widely used abrasive processing method. Polishing is required to improve the surface quality of metal and non-metal products, precision electromechanical products and daily necessities. The main purpose of polishing is to remove the processing marks of the previous process, improve the roughness of the part surface, obtain a bright and smooth processing surface, increase the beauty, and improve the fatigue resistance and corrosion resistance of the workpiece.

[0003] The outer surface of metal parts will cause oxidation reaction to form an oxide layer, commonly known as black skin, when exposed to a hot and humid environment for a long time or stored improperly. The oxide layer will accelerate the corrosion process of the metal and cause the strength of the metal to decrease.

[0004] The removal of black skin is generally carried out by polishing the surface of the metal part with a polishing machine. The existing cam polishing machine cannot automatically adjust the horizontal position of the cam and the height position of the metal part during the polishing of the curved surface of the metal part. The grinding position of the cam can only be adjusted according to the polishing situation based on the worker's experience, resulting in low polishing efficiency and high labor cost investment.
